ROBERT HENDERSON DUNCAN, OEEPPING, NEAR SYDNEY, NEW SOUTH WALES,

AUSTRALIA.

SECURITY BOX OR CASE.

Application filed January 29, 1919.

To all whom it may concern:

Be it known that I, ROBERT HENDERSON DUNCAN, a citizen of the Commonwealth of Australia, residing at Epping, near Sydney, in the State of New South WV ales, Commonwealth of Australia,have invented certain new and useful Improvements in a Security Box or Case, of which the following is a specification.

This invention relates to improvements in boxes or cases used for the transportation of goods of various kinds such as, eggs, fruit, food-stuffs, merchandise, and the like, and articles which it is desired should be delivered at their destination in their originally packed condition, unaffected by the tampering efforts of would-be purloiners and if in the event of such improper interference with the goods being made while the boxes are in transit, it will be possible for the consignee (before accepting delivery) to ascertain that the case has been tampered with en route.

The improvements include means for safeguarding the united parts comprising the box or case, by suitably using and fixedly locating banding wire and cleats in positions which will prevent the easy detachment of the boards, either by instrumental force, or by the rough usage common to the transportation of goods, and the handling of same carelessly. Further, provision is made to secure the detachable lid part in its rightful position by means of both internally and externally arranged attachments, combined with dual fastenings, with which is associated a locking device adapted to be in engagement with an address plate, a retaining spring, and a secretly confined cord attachment, having its end, or ends, disposed in a safeguarding sinkage adapted to be sealed, and so covering the said ends of the cord, thus necessitating the severance of the attachment when the box reaches the consignee.

The invention is illustrated by the accompanying drawings, in which similar letters of reference are used to indicate the same parts when shown in different figures, and in which Figure lis a perspective view of the.

box lid as seen on its underside, showing attachment parts and catch fastenings with associated plate.

Fig. 13 is a further detail showing fastenings in Fig. 12 in the disengaged and unlocked positions, but with lever and attachments omitted.

, Fig. 14- is a plan of sliding piece in its engaged position.

The form of box or case shown in the drawings is of the kind suitable for the transportation of eggs, but the invention is e vention. and the wire banding and cleats similarly utilized.

In Figs. 3, at and 5, the box ends A, are overlapped by the side-pieces A and the bottom portion A which renders unnecessary the use of banding wire B, such as is inserted in the grooves A (saw-cuts) formed in the sides and bottoms. Security clips B clenched within the box, prevent displace ment of the wire (shown dotted in the side grooves) which is continued over the top edges and secured with clips to form angle pieces B thus preventing forcible detachment, of theunited Wood parts.

In egg boxes the transverse end pieces A, are used for lifting" purposes, but I provide in them the hand grip formations A Figs. 8, 12, 13 to prevent slipping taking place as the boxes are handled.

In Figs. 5 and 10, an end piece is utilized to secrete and to further secure the angle pieces C, attached to an end box part. These are set at any suitable distance apart so as to slidably engage with their grooved companion plates C fastened to the underside face of the lid D. The said plateswhen fully seated prevent endwise movement of the lid,

meansof a stem piece or spindle E, passing.

side Fig. 10, and also prevents its uplift at that end. 7

In the construction of egg boxes having lids of the Hush top type, transverse stiffening pieces are attached to the underside of the lid, thus necessitating the lowering of the end pieces such as A to provide an upstanding margin or space which they occupy when the lid is in its position, but I find it desirable to avoid this form of construction'by having a flush under-surface lid with its transverse pieces D secured with. angularly disposed corner clips Dipassing through both woods and clenched underneath. j 7

Intermediate nail'fastenings serve to complete the construction. Besides being able to handle the lid mo're conveniently they serve .to guard the fastening and secreting appliances by which the lid is rendered immovable and the contents of the box safeguarded. The fastening attachments are essentially combined both with the lid and the box, and although the drawings show only a single set of such whenassociated with an egg box, it is obvious that when applied to boxes or cases of large dimensions it would be desirable to use a suitable number ac cording to requirements.

' The lid attachment details appear in Figs. 7 to 13 inclusive, and the box attachment details in Figs. 8, 10, 12 to 1%. The several parts of the lid attachments, are the beforementioned angle pieces C, with their grooved companion plates C by which the lid is held in position at one end. At'the other endsecurity of fastening is obtained by downwardly through the washer E and the lid D. Outside the lid, the locking lever F, secured to the spindle, is made serviceable by its gapped formation F to engage with the upstanding part H, of the laterally sliding bolt H which forms part of the box attachment. The aforesaid spindle is held in position by the angle plate G secured to the underside of the lid, the downwardly extending length being squared to hold the barrel formation E with its extending catch E the parts being further secured by the screw threaded nut E attached to the threaded spindle end. The aforesaid angle plate G, is provided with the hook shaped part G which serves the dual purpose of a centralizer and sliding bolt holder when lowered into thegapped formation H provided bet-ween'barrel parts H and H*, which are homogeneous with the plate H secured to the boxlpart A, as in Figs. 12 to 14, by the screws The plate H is further provided with the angle piece H with its gap H in which is to be located the barrel part E to serve as a centralizer in association with the before mentioned hook shaped part G as in Fig. 11, which shows the catch E in its disengaged position to allow of the barrel shaped part entering the gap H as is also indicated in Fig. 14, in dotted lines. This is the essentially normal position ofthe catch part E before the lid is placed in its right position for locking by the rotation of the lever F, which has the effect of placing the said catch beneath plate H as shown in Fig. 8.

In Fig. 12, the box attachments are shown in combination with the lid attachments, all in their secured and locked positions,'but in Fig. 13, the spindle E, and the parts belonging thereto are wholly omitted to show more clearly the centralizing part G of' the anglepiece Gr, fitting into the gap H as it would appearwhen the lid is lowered before the bolting and locking action can take place. The bolt H is there shown withdrawn, in which case the lever F, would be in the position as-indicated by the dotted lines in Fig. 7. To allow the bolt stem H, to be operated from above the lid D, the channel I, is provided in the lid, and the cutaway I in the batten D The horizonface to allow the address plate to pass, the

turned down ends piercing the -lid andare secured by clenching underneath. The

spring M, serves to hold the lever in its locked position, by being placed in engagement with the turned-up end F of the lever, the security cord N, being passed around same, and thence through the secreting channel O, and down the channel P, into the sealing receptacle Q, when it may be covered with sealing wax on which may be impressed the consignors initials or monogram or trade mark, as may be considered desirable. As before stated the lids may be either wholly removable or they may be loosely attached to the boxes by means of looped attachments D inserted in holes provided in suitable positions.

The address plate K as shown in Fig. 7 consists of a metal plate K, having an engagement hook K to receive the lever F when rotated into the engagement and looking position shown in Fig. 7. The said plate is passed under the bridge-piece L which serves as a guide and which is secured to the lid' D. The curved end K is shown in engagement with the said bridge-piece. The tag part K is provided to facilitate the withdrawal of the plate after the lever F has been released from engagement with the spring M, and the cord attachment N, confined in the channel 0 and sealed in the receptacle Q formed in the side of the case.

Having now described my invention, what I consider novel and desire to secure by Letters Patent is 1. In a guarantee case or box, case and lid attachment interlocking parts, coincidently arranged on the separable parts thereof; the lid part having transverse end pieces, angularly disposed corner clips clenched on the under surface of the lid for securing the end pieces, one such end piecelocated adjacently to the lid looking at tachmenthaving a cord secreting channel thereunder and which is continued downwardly to the sealing formation, a bolt, the lid having a channel for bolt stem to slide in, the end piece being cut away for said stem, a spindle, a gapped lever attached outwardly to the spindle, the spindle located downwardly in the lid, a hook shaped centralizing 'plate secured to underside of lid, a combined barrel and catch attached to spindle and operated by the said lever,

grooved companion plates attached to underside of lid, and securing angle plates attached to the box parts contiguous thereto, and engaged by the companion plates.

2. In a guarantee case or box having both the case and lid attachment interlocking parts, coincidently arranged on the separable parts thereof; the combination comprising the interiorly located bolt casing having a tubular portion and having a gapped formation, a centralizing hook shaped plate received and secured in the gapped formation of the casing and attached to the case lid, a gapped angle plate located below said gap and forming an integral part of said casing, a slidable bolt moving in the tubular portion of casing and having an upstanding stem adapted to be operated from outside the box, the said bolt slidably engaging with the aforesaid centralizing plate, an exteriorly located operating lever gapped to engage with the upstanding stem of the slidable bolt, and further having a turned up end part to form cord attachment, and a spindle on said lever having on its downward end a combined tubular and catch formation in engagement with the lowermost gapped plate which is part of bolt casing.

3. In a guarantee case or box having both the case and lid attachment interlocking parts, coincidently arranged on the separable parts thereof: the combination comprising the parts claimed in claim 2, with an address plate having a central withdrawing hook formation, a bent end part to be in engagement with a lid bridge, a forwardly located hook formation to be engaged by the locking lever, a recoil spring to retain said locking lever in its engaged position, an engaged cord attached to such lever, and thereafter secretly located in the channeled parts provided in the lid and box, and having the ends sealed in the sinkage provided, and as described.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT HENDERSON DUNCAN.
